Q35.Consider the following reactions: conc.H2SO4 −(a) (CH3)3CCH(OH)CH3 → alc.KOH −(b) (CH3)2CHCH(Br)CH3 → (CH3)3O⊖K⊕ −(c) (CH3)2CHCH(Br)CH3 → (d) Which of the reaction(s) will not produce Saytzeff product? (1) (a), (c) and (d) (2) (d) only (3) (c) only (4) (b) and (d)
What This Question Tests
This question assesses the understanding of regioselectivity in elimination reactions (E1/E2) and the factors that determine whether a Saytzeff or Hofmann product is formed, particularly the role of bulky bases.
